Processor Number Feature

Common Options : Enabled, Disabled

Quick Review

This BIOS feature allows you to control the use of the processor's embedded unique identification number. Therefore, it is only valid if you are using a processor that features such a feature.

This infamous "feature" debuted in the Intel Pentium III processor and is mainly found only in that processor. The Transmeta Crusoe processor also supports this feature. But most manufacturers have refrained from integrating such a "feature" in their processors. Even Intel has declined to add this feature to the Intel Pentium 4 processors.

If enabled, the processor's identification number can be read by external programs. It used to be required for certain secure transactions. However, this is no longer true as the initiative has long been abandoned.

If disabled, the processor's identification number cannot be read by external programs.

It is highly advisable that you disable this feature because it no longer has a use. Even worse, it can actually be misused to track your online activities. Disabling this feature will safeguard your privacy by preventing the identification of your computer by the processor's identification number.
